Brent's algorithm is universal, sets no arbitrary limit and requires no
hash and is implemented in few lines at a slight cost of going through
the cycle potentially up to 2 (or was it 3?) times.

it's not more difficult than setting SYMLOOP_MAX.
I'm ok to implement it in gnulib, just not until the end of my exams
